Parts and Service

As a noun, a part is a section of a greater whole. It is normally an intentional segment rather than one caused by dissection. See e.g. Standard Industrial Classification for various categories.

As a verb, to part means to divide or separate.

In the performing arts

Music

In music, a part is the line of music played by an individual instrument or voice (or group of identical instruments or voices) within a larger work. It also refers to the printed copy of the music for each instrument, as distinct from the score, which holds the music for all instruments. For example in a string ensemble you would have separate parts for Violin 1, Violin 2, Viola and Cello, even though there might be several of each instrument (and therefore several copies of each part).

See also: voice, ensemble, polyphony, counterpoint.

Film, theatre and television

In film, theatre and television, a part is an actor's role.

In dance

A part is a dancer's role, particularly in a major work such as a classical ballet.

In mathematics

A part is any geometric object such as a point, line, arc, circle, polygon, polyhedron, or polytope that can be joined together to form a whole. It may also be defined as a bounded region in the plane, for two-dimensional geometry, or as a bounded region in space, for three-dimensional geometry.

There are two kinds of parts: complex and simple. Complex parts can be dissected into simple parts, and simple parts cannot be dissected further.

"Imaginary part" is a common but somewhat odd term, because although it provides part of the information about a complex number, it is not a part in the normal sense.

In fashion

The part of a person's hair is the "watershed" line at which the hair is parted, or divided. Some people part their hair in the middle (a "center part," following the natural part of the hair), and some part their hair at one side or the other. See also: hairstyle.

This article is about a term used in economics. For other uses, see service (disambiguation).

In economics and marketing, a service is the non-material equivalent of a good. Service provision has been defined as an economic activity that does not result in ownership, and this is what differentiates it from providing physical goods. It is claimed to be a process that creates benefits by facilitating either a change in customers, a change in their physical possessions, or a change in their intangible assets.

By supplying some level of skill, ingenuity, and experience, providers of a service participate in an economy without the restrictions of carrying stock (inventory) or the need to concern themselves with bulky raw materials. On the other hand, their investment in expertise does require marketing and upgrading in the face of competition which has equally few physical restrictions.

Providers of services make up the Tertiary sector of industry.

Key attributes

Services can be described in terms of their main attributes.

• Intangibility - They cannot be seen, handled, smelled, etc. There is no need for storage. Because services are difficult to conceptualize, marketing them requires creative visualization to effectively evoke a concrete image in the customer's mind. From the customer's point of view, this attribute makes it difficult to evaluate or compare services prior to experiencing the service.
• Perishability - Unsold service time is "lost", that is, it cannot be regained. It is a lost economic opportunity. For example a doctor that is booked for only two hours a day cannot later work those hours— she has lost her economic opportunity. Other service examples are airplane seats (once the plane departs, those empty seats cannot be sold), and theatre seats (sales end at a certain point).
• Lack of transportability - Services must be consumed at the point of "production".
• Lack of homogeneity - Services are typically modified for each client or each new situation (customised). Mass production of services is very difficult. This can be seen as a problem of inconsistent quality. Both inputs and outputs to the processes involved providing services are highly variable, as are the relationships between these processes, making it difficult to maintain consistent quality.
• Labour intensity - Services usually involve considerable human activity, rather than precisely determined process. Human resource management is important. The human factor is often the key success factor in service industries. It is difficult to achieve economies of scale or gain dominant market share.
• Demand fluctuations - It is very difficult to estimate demand. Demand can vary by season, time of day, business cycle, etc.
• Buyer involvement - Most service provision requires a high degree of interaction between client and service provider.

Service delivery

The delivery of a service typically involves five factors:

• The service providers (e.g. the people)
• Equipment used to provide the service (e.g. vehicles, cash registers)
• The physical facilities (e.g. buildings, parking, waiting rooms)
• The client
• Other customers at the service delivery location

The service encounter is defined as all activities involved in the service delivery process. Some service managers use the term "moment of truth" to indicate that defining point in a specific service encounter where interactions are most intense.

Many business theorists view service provision as a performance or act (sometimes humorously referred to as dramalurgy, perhaps in reference to dramaturgy). The location of the service delivery is referred to as the stage and the objects that facilitate the service process are called props. A script is a sequence of behaviours followed by all those involved, including the client(s). Some service dramas are tightly scripted, others are more ad lib. Role congruence occurs when each actor follows a script that harmonizes with the roles played by the other actors.

In some service industries, especially health care, dispute resolution, and social services, a popular concept is the idea of the caseload, which refers to the total number of patients, clients, litigants, or claimants that a given employee is presently responsible for. On a daily basis, in all those fields, employees must balance the needs of any individual case against the needs of all other current cases as well as their own personal needs.

Under English law, if a service provider is induced to deliver services to a dishonest client by a deception, this is an offence under the Theft Act 1978.

Service-Goods continuum

The service-goods continuum

The dichotomy between physical goods and intangible services should not be given too much credence. These are not discrete categories. Most business theorists see a continuum with pure service on one terminal point and pure commodity good on the other terminal point. Most products fall between these two extremes. For example, a restaurant provides a physical good (the food), but also provides services in the form of ambience, the setting and clearing of the table, etc. And although some utilities actually deliver physical goods — like water utilities which actually deliver water — utilities are usually treated as services.

In a narrower sense, service refers to quality of customer service: the measured appropriateness of assistance and support provided to a customer. This particular usage occurs frequently in retailing.
